version

This class contains version and authorship information.
It contains only static data elements and basically just a central
place to put this kind of information so it can be updated easily
for each release.
Version numbers used here are broken into 3 parts: major, minor, and
update, and are written as v.. (e.g. v0.10a).
Major numbers will change at the time of major reworking of some
part of the system. Minor numbers for each public release or
change big enough to cause incompatibilities. Finally update
letter will be incremented for small bug fixes and changes that
probably wouldn't be noticed by a user.
